I tried a few chip buds on apple and pear rootstocks along with my other grafts this spring. These were bench grafted about 1 month ago. Allowed to rest and then planted into my nursery about 2 weeks ago. Most of the rootstocks that had chip buds grafted onto them are starting to leaf out. Some of my chip buds are swelling a bit, but have not broken yet. Should I allow leaf growth to begin above or below the chip bud? How long do I need to wait before trying to force the chip buds.

Thanks!
